ROUTINE AND PERIODIC
MAINTENANCE
BEFORE EACH USE
Check over machine and accessories for any obvious condi-
tion that may prevent safe performance or operation. Repair
or replace items as necessary to correct any abnormal con-
dition.
AFTER 5 MINUTES OF WELDING
or when spatter accumulates in the gas nozzle:
Clean the contact tip and gas nozzle to avoid bridging
between the nozzle and contact tip. Bridging results in a
shorted nozzle, poor welds and overheated gun. Hint: Anti-
stick spray or gel available from a welding supplier may
reduce buildup and aid in spatter removal.
